B. Fructose is an example of a carbohydrate. Carbohydrates are categorized as organic molecules.
Answer:
leaves capture the most solar energy to power photosynthesis
night blindness-vitamin A deficiency
color blindness - trouble distinguishing colors
hyperopia-eyeball too short
myopia-eyeball too long
astigmatism-light refracted aspherically.
<h3><u>Explanation:</u></h3>
Night blindness is defined as the disease which involves the mal production of retinol in the rod cells of retina. This leads to the decreased sensitivity of eye to dim light.
Similarly, colour blindness is a genetic disease which is characterised by absence of a particular pigment in cone cells. This restricts the vision of a particular colour.
Hyperopia or hypermetropia is the shortening of eyeball which leads to the focusing of light rays behind the retina. So convex lenses are required to focus them on retina.
Myopia is the opposite of hypermetropia where the eyeball is elongated and the light rays doesn't reach the retina. So concave lens are required to focus the rays on retina.
Astigmatism is the case where the curvature of lens isn't correct, and the lens required for the correction is cylindrical lens
Answer:
Merkel cells located in the epidermis.
- It is called sensory function.
- The Merkel cells send information to the brain about temperature and touch.
- After brain decode that we can feel it.
Answer:
See the answer below
Explanation:
Mendel's second law of genetics is also known as the law of independent assortment of genes.
In this law, Mendel opined that genes are independently inherited. In other words, Mendel said that the factors that dictate the physical attributes of living organisms are inherited independently.
This means, for example, that the color of your eyes is independently inherited from the color of your skin, your skin color is independent of your hair color, etc.
Mendel was able to prove this law by performing a dihybrid cross using the pea plant.
A true-breeding plant that is dominant for round and yellow traits (RRYY) was crossed with another true-breeding plant that is recessive for wrinkled and green traits (rryy).
All the F1 offspring were round with yellow color and the cross was advanced to F2. The F2 plants segregated in the ratio of 3:1 for the round trait to wrinkled traits and also 3:1 for the yellow to green traits respectively.
The outcome was the same as carrying out a monohybrid cross for each trait independently. Hence, Mendel concluded that traits are inherited independently of each other.
